Category: AI
You are here if AI showed up in your job and the names on the screen do not match the buttons. This category is practical. It is not a model-release calendar, and it is not one lesson pasted under a new product name. The series split the pile so a Claude post and a ChatGPT post can teach different work.
Everyday paths are for a person with no account yet, or a person whose chat forgot a file: setup, prompting, memory, agents, safety, and which product fits a job. Product paths stay on one tool: Claude, ChatGPT, Gemini, or Grok, from a first login to the surface you should not open. Open-weight paths are Llama, DeepSeek, Qwen, Kimi, and GLM: what the name refers to, and when a normal paid chat is the easier tool. Engineering paths are for running a model, retrieving from your own files, and fine-tuning. Several of those hubs are still waiting on a first live part, and the hub page says so.
Where to start: no account yet, use AI setup from zero. You already pay for one product, open that product’s series and use the first part. You want the idea before the brand, use Practical AI. You want every series in order, use Learn and the AI tracks.
What to do with Google Gemini in your first week of using it
Useful Gemini skill is five short days with one real deliverable outside chat each day, not one enthusiastic poem about your title.
Which kind of AI tool fits your job: a chat, an agent, or a coding agent?
Chat, agent, work mode, and coding agent are four doors. Pick by the artifact. A short rewrite does not need a folder-wide agent run.
How to prompt AI for study notes, work email, plans, and shopping research
Study, email, plans, and shopping share one skill: one job per chat, named constraints, and verify before you spend or send.
Where your files go when you upload them to ChatGPT, Gemini, or Claude
Know whether a file left as paste, upload, Project, or Memory. Paste a snippet, not a giant CRM export, and check training toggles.
